Dual code authentication system

ABSTRACT

A verification method and system are disclosed that verify a user. The user is provided a verification code via, for example, a website, to be communicated to a provided electronic contact via a secondary mode of communication, such as through an SMS-enabled device. If the correct verification code is communicated by the user, the user receives a return message (e.g., a return SMS message) containing a second verification code, which the user submits to a website or on-line form or to another verification system for authentication.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional PatentApplication No. 61/564,531, entitled “DUAL PIN CODE SMS AUTHENTICATIONSYSTEM” filed Nov. 29, 2011, which is incorporated herein by referencein its entirety.

BACKGROUND

With the increasing popularity of the Internet, it has become moreimportant to require users to register with the websites they use inorder for them to obtain information from the website, order goodsthrough the website, store information through the website, etc. In someinstances, the owners of the website wish to use the registrationinformation to selectively target promotions or advertisements based onregistration information and thus, get a secondary gain in addition tohaving the registrant or user visit the website or use the servicesprovided through the website. In other instances, the user'sregistration information is not used for secondary gain, but instead iskept completely confidential and is used only for the purposes ofallowing the registrant or user to enter the website and obtaininformation or goods and services through the website.

User authentication is fundamental to every Internet transaction.Individuals and businesses who wish to engage in trade on-line mustauthenticate themselves reliably by presenting credentials to establishtheir identity. Despite this, when doing business on the Internet,potential registrants or users often register with untraceable or falsee-mail addresses and phone numbers. This can compromise the intendedpurpose of the registration, create a breach of security, and constitutefraud on the website owners.

DETAILED DESCRIPTION

A dual code verification system and method are described that verify anidentity of a user of a service. For example, the user of the servicemay be a registrant of a website who is accessing the website via apersonal computer or a customer of an online retailer attempting to buya product. The registrant may be verified via short message service(SMS) messages with a mobile device associated with the registrant. Insome implementations, the dual code verification system authenticates apreviously-registered user using information received from a priorregistration by the user.

The dual code verification system verifies a user of a service through aprocess under which two verification codes are transmitted to andreceived from the user. The dual code verification system transmits thefirst verification code along with electronic contact information to theuser. For example, the dual code verification system may display atelephone number and an alphanumeric code on a website visited by a useror within an application used by a user on a mobile device or computer.The dual code verification system also requests that the usercommunicate the verification code back to the dual code verificationsystem using the electronic contact information. The dual codeverification system receives a verification code sent by the user usingthe electronic contact information. The dual code verification systemcompares the received and transmitted verification codes. If theverification codes substantially match, the dual code verificationsystem transmits the second verification code to the user, sending thecode to an electronic address associated with a device or account fromwhich the first verification code was received. For example, if a userhas sent an SMS message containing a verification code from a mobiledevice, the dual code verification system may transmit the secondverification code via SMS message to the mobile device using a telephonenumber associated with the mobile device. The dual code verificationsystem instructs the user to submit the second received verificationcode in a different manner than how the user received it from the dualcode verification system. For example, the dual code verification systemmay instruct the user to submit the second verification code via awebsite visited by the user or an application used by the user. This maybe the same website or application used to transmit the firstverification code to the user. The dual code verification systemverifies the user if the second received verification code substantiallymatches the second verification code transmitted to the user.

Various embodiments of the invention will now be described. Thefollowing description provides specific details for a thoroughunderstanding and an enabling description of these embodiments. Oneskilled in the art will understand, however, that the invention may bepracticed without many of these details. Additionally, some well-knownstructures or functions may not be shown or described in detail, so asto avoid unnecessarily obscuring the relevant description of the variousembodiments. The terminology used in the description presented below isintended to be interpreted in its broadest reasonable manner, eventhough it is being used in conjunction with a detailed description ofcertain specific embodiments of the invention. Although many embodimentsand implementations of the system are described with respect to sendingand receiving a PIN code, a verification code, and the like, in someimplementations, other information may be used to verify a user. Forexample, the dual code verification system may transmit an image of anobject to a mobile device and instruct the user to transmit back to thesystem the name of the object.

In some embodiments, a registration form is provided on a website. Auser of the website, such as a registrant or a user browsing thewebsite, is informed via the website to send an electronic messagecontaining the verification code (e.g., a Personal Identification Number(“PIN”)) to a contact number. The verification code may be a generatedIdentification PIN Code (“IPC”). Additionally, the contact number can bea long code phone number or a shorter phone number (e.g., short code).Both the IPC verification code and contact number are provided to thewebsite registrant upon the registrant's entry of his or her name,username, and password. The electronic message may comprise an SMSmessage sent by the registrant using the registrant's SMS-enabledhandset or cellular telephone, or other SMS-or similarly enabled device.Although the registrant or user typically establishes an SMS-basedconnection with the dual code verification system via the registrant'sor user's handset or cellular telephone, other embodiments of thepresent invention include providing a system telephone number for theregistrant or user to call to enter this information. Once the dual codeverification system receives the registrant's electronic messagecontaining the verification code or IPC, another verification code orAuthentication PIN Code (“APC”) is generated and returned via anelectronic message to the registrant's same handset, cellular telephone,or other similarly enabled device that was initially used by theregistrant to send the first verification code, or IPC. The registrantor user then inputs the second verification code, or APC, into theregistration screen on the website. The result is either authenticationfor a correct entry, or potential rejection for an incorrect entry,according to the verification-requesting-website's preferences.

In some embodiments, after initial registration wherein a user hasalready successfully established a username and password for a websitethrough the above or a similar process, and wherein that website hasretained and stored that user's log-in information and previously usedhandset or cellular telephone number, the user attempts to later gainadmittance to the website on a subsequent visit. When the user attemptsto access that particular website, the user is informed by the websiteto send an electronic message including a verification code or generatedIPC to a contact number. Both the verification code and the contactnumber are provided by the website once the user inputs his or herpreviously established username and password. The electronic message maycomprise an SMS message sent by the user via his or her SMS-enabledhandset or cellular telephone, or other SMS-or similarly enabled device.The electronic message sent by the user contains the verification codeor IPC. Although the user may establish an SMS-based connection with thedual code verification system via the user's handset or cellulartelephone, other embodiments of the present invention include providinga dual code verification system telephone number for the user to call tomanually enter this information. Once the dual code verification systemreceives the user's electronic message, the system attempts to verifythe user's handset, cellular telephone, or other similarly SMS-enableddevice. And if verified, a second verification code or APC is generatedand returned via electronic message to the user's same handset, cellulartelephone, or other similarly SMS-enabled device. The APC verificationcode is then input by the user into the registration screen on thewebsite, resulting in either authentication for a correct entry, orpotential rejection for an incorrect entry, according to theverification-requesting-website's preferences.

Suitable Environments

FIG. 1 and the following discussion provide a brief, general descriptionof a suitable computing environment 100 in which a dual codeverification system is implemented. The computing environment 100includes a mobile device 105 (e.g., a smartphone) and a computing device110 (e.g., a personal computer), through which a user may access aserver computer 115 and one or more third party server computers 125.The server computers 115 and 125 utilize data storage areas 120 and 130,respectively. As will be described in more detail herein, the dual codeverification system may in part reside on the server computer 115, andverify the identity of a user who is utilizing a personal computer 110or mobile device 105 to access websites, applications, or other servicesprovided by the third party server computers 125. The data storage area120 contains data utilized by the dual code verification system, and, insome implementations, software necessary to perform functions of thesystem. For example, the data storage area 120 may contain dataassociated with a user, such as a mobile communication number associatedwith a user's mobile device 105. As will be described in more detailherein, as part of a verification process, the system may utilize themobile communication number for sending a verification message to theuser's mobile device 105. The system may also receive a verificationmessage from the mobile communication device.

The mobile communication device 105, personal computer 110, servercomputer 115 and third party server computers 125 communicate with eachother through one or more public or private, wired or wireless networks140, including, for example, the Internet. The mobile device 105communicates wirelessly with a base station or access point using awireless mobile telephone standard, such as the Global System for MobileCommunications (GSM), Long Term Evolution (LTE), IEEE 802.11, or anotherwireless standard, and the base station or access point communicateswith the server computer 115 and third party server computers 125 viathe networks 140. Computers 110 communicate through the networks 140using, for example, TCP/IP protocols. The mobile device 105 utilizesapplications or other software, which operate through the use ofcomputer executable instructions. Some such applications may be directedtoward the verification process (e.g. providing a button on the screenfor a user to press as part of completing a dual code verificationprocess). As will be described in more detail herein, the dual codeverification system residing at least in part on the server computer 115may also utilize software which operates through the use ofcomputer-executable instructions as part of the authentication andidentity process.

Although not required, aspects and implementations of the invention willgenerally be described in the general context of computer-executableinstructions, such as routines executed by the mobile device 105, thecomputing device 110, the server computer 115, the third party servercomputers 125, or other computing systems. The invention can also beembodied in a special purpose computer or data processor that isspecifically programmed, configured, or constructed to perform one ormore of the computer-executable instructions explained in detail herein.Indeed, the terms “computer” and “computing device,” as used generallyherein, refer to devices that have a processor and non-transitorymemory, like any of the above devices, as well as any data processor orany device capable of communicating with a network. Data processorsinclude programmable general-purpose or special-purpose microprocessors,programmable controllers, application-specific integrated circuits(ASICs), programmable logic devices (PLDs), or the like, or acombination of such devices. Computer-executable instructions may bestored in memory, such as random access memory (RAM), read-only memory(ROM), flash memory, or the like, or a combination of such components.Computer-executable instructions may also be stored in one or morestorage devices, such as magnetic or optical-based disks, flash memorydevices, or any other type of non-volatile storage medium ornon-transitory medium for data. Computer-executable instructions mayinclude one or more program modules, which include routines, programs,objects, components, data structures, and so on that perform particulartasks or implement particular abstract data types.

The system and method can also be practiced in distributed computingenvironments, where tasks or modules are performed by remote processingdevices, which are linked through a communications network, such as aLocal Area Network (“LAN”), Wide Area Network (“WAN”), or the Internet.In a distributed computing environment, program modules or subroutinesmay be located in both local and remote memory storage devices. Aspectsof the invention described herein may be stored or distributed ontangible, non-transitory computer-readable media, including magnetic andoptically readable and removable computer discs, stored in firmware inchips (e.g., EEPROM chips).

Dual Code Verification Systems

FIG. 2 is a block diagram of various modules of a dual code verificationsystem 200. The dual code verification system 200 verifies an identityof a user of a service. The dual code verification system 200 includes averification code generation component 210, a communication component220, a verification code comparison component 230, and a user analysiscomponent 240. The dual code verification system 200 accesses and/orstores data in user data storage area 250.

The dual code verification system 200 sends and receives verificationmessages, receives user data, and sends verification alerts. Averification message can include various types of information, includinga verification code (e.g., an alphanumeric PIN), contact information(e.g., a telephone number), and instructions for transmitting averification message, including, for example, an electronic address. Insome implementations, a verification message is sent to or received froma user of a website or application. In some implementations, averification message is an SMS message. In some implementations, averification message is data sent to or received from a third party tofacilitate the verification of a user. For example, a verificationmessage may include web data that is sent to a website for display tothe user or to otherwise facilitate the verification of the user. Userdata includes data associated with the user or submitted by the user.User data may include contact information for a user, such as a mobiledevice identifier (e.g., a phone number), a username, an email address,and so forth. User data may also include information submitted by auser, such as information submitted by a user via a form displayed on awebpage. A verification alert includes a message sent to a user or athird party indicating whether a user is verified or not.

The verification code generation component 210 generates or identifies averification code to be transmitted to a user. It may generate averification code using a random number generator or an algorithm forgenerating verification codes. The verification code generationcomponent may also identify a stored verification code that is to besent to a user.

The communication component 220 transmits and receives verificationmessages and user data. It may transmit and receive verificationmessages to and from third parties (e.g., websites) and users (e.g.,registrants). It also is configured to receive user data, such as datasubmitted by a registrant (e.g., via a form displayed on a website). Itmay also transmit web or application data to a third party or a user.

The verification code comparison component 230 compares transmitted andreceived verification codes. For example, the verification codecomparison component may compare a verification code transmitted via SMSmessage to a user with a verification code received from a user via awebsite form. It may also compare a verification code provided via anapplication or webpage to a user with a verification code received froma user via an SMS or other message. The verification code comparisoncomponent is configured to determine whether a transmitted verificationcode substantially matches a received verification code. Theverification code comparison component also generates verificationalerts. For example, if a first transmitted verification codesubstantially matches a first received verification code and a secondtransmitted verification code substantially matches a second receivedverification code, the verification code comparison component generatesan alert that the user is verified. In some implementations, theverification code comparison component determines that a transmittedverification code and a received verification code substantially matchwhen the received verification code includes a substantial amount ofdata that is identical to data of the transmitted verification code. Forexample, a transmitted verification code consisting of an alphanumericstring may be determined to substantially match a received verificationcode if the received verification code includes a majority of thecharacters of the transmitted alphanumeric string.

The user analysis component 240 is configured to analyze user data or averification message received from a user or a third party or identifiedin data storage area 250 to identify information associated with a user.For example, the user analysis component may analyze a message toidentify a phone number from which the verification message was sent.The user analysis component also gathers data from data storage area 250related to a previously-registered user who is being authenticated bythe dual code verification system.

Suitable Processes

FIG. 3 is a flow diagram of a process 300 implemented by the dual codeverification system 200 for verifying a user attempting to registerusing an on-line registration form that is accessed through a website.In some implementations, the system performs the process without usingan on-line form. In some implementations, the verification andnotification processes described herein can also be achieved throughother registration forms, such as a handwritten form. In someembodiments, the registrant or user is informed via the registrationwebsite to communicate an electronic contact (as defined above), such asthrough an SMS message using an SMS-enabled handset or similar device,to the contact number (as defined above) provided on the website. Aconcern that the present disclosure addresses is that in a typicalsystem where the registrant or user is contacted via a means ofcommunication (including but not limited to e-mail), that means ofcommunication can easily be intercepted, stopped, filtered, trashed, ordeleted by a third party. However, where the registrant or user directlysends the verification code via electronic message or SMS, as in thepresent invention, and the dual code verification system or websiteresponds by generating a different verification code that is sent backto the registrant's or user's same communication device, there isincreased security as a result of the dual code verificationconfirmation. Additional increased security is further derived where thedual code authentication system prevents “man in the middle” attacksthat cannot be solved by an easily intercepted single layer ofauthentication.

In some implementations, a user is a registrant, end-user, or userfilling out a registration form in order to register with a website,on-line merchant, e-commerce site, business, etc. A registrant includes,for example, a consumer, which can be an individual, but can also be acompany, organization, the government, and so on. Sometimes, theregistrant is registering with another business. For example, theregistrant can be an individual attempting to access a website and setup an account with a financial institution. The various identities andtypes of user and business may vary, as may the purpose of registrationand verification.

As illustrated in FIG. 3, at a block 301, the user is provided with aregistration form. For example, the form may be provided via a website.At a block 302, the system receives a submission from theregistrant/user in response to the form. At a decision block 303, thesystem determines whether the registrant has at least partiallycompleted the registration form. If the user has not at least partiallycompleted the form, at a block 307, the user is notified that he or shedid not complete the verification. However, if the user does at leastpartially fill out the form, the process proceeds to a block 309, andthe system performs a dual code verification. Through the dual codeverification, the registrant is eventually allowed to log-in to thewebsite at a block 313 after verification, or is denied access at ablock 315 to the website if he or she cannot be verified. Thus, at adecision block 310, the system determines whether the registrant/userhas been verified, and the process proceeds to block 313 if the systemis able to verify the user and to block 315 if the system is not able toverify the user. For verification, the user is routed to or is able toaccess a webpage that requests dual code verification. The systemperforms a dual code verification as described herein.

FIG. 4 is a flow diagram of a process 400 implemented by the system forperforming a dual code verification. The process begins at a block 402,and the user is provided an on-line registration form via a website. Ata decision block 406, the system determines whether it has received aname, username, and password from the registrant/user. If the system hasnot received a name, username, and password from the registrant/user,the process 400 proceeds to a block 426 and the registrant is notverified. If the system does receive this information, the websiterequests an IPC from the system, and, at a block 408, the systemgenerates the IPC which is passed back to the website. At a block 410,the IPC is displayed by the website. In some embodiments, the websitegenerates the IPC, passing that information back to the system. In someembodiments, the IPC is solely alphabetic. In other embodiments, the IPCis solely numeric. The IPC may also be alphanumeric. At a block 412, thewebsite prompts the registrant to send the IPC in an SMS message usinghis or her mobile device (e.g., handset or cellular telephone, orequivalent SMS-capable device), to the contact number displayed on thewebsite. At a block 414, the system receives from the user an SMSmessage addressed to the contact number that includes an IPC. At adecision block 416, the system determines whether the transmitted IPCcode substantially matches the received IPC code. In someimplementations, the system looks up the IPC to ensure it substantiallymatches with the generated IPC originally presented to the user, andadditionally takes note of the phone number or other identifyingcommunication information used by the user to send the SMS message. Insome implementations, the system passes the IPC SMS message sent by theuser to the website to verify that the IPC code matches. If the usersent IPC matches the originally generated IPC, at a block 418, thesystem or website generates a second verification code or APC. At ablock 420, this APC is returned back to the user's same handset or otherSMS-capable device used to originally communicate the IPC by the uservia return-SMS message. In some embodiments, the APC will only bereturned to the same device or account associated with the submission ofthe IPC. In this way, the risk of third party interception is greatlyreduced. At a block 422, the registrant is prompted to input the APCinto the on-line registration form or website. The on-line registrationform is preferably part of the website, but can be part of theverification system by some other means. The verification andauthentication is completed if the user enters the correct APCverification code, as verified by the system generating the IPC and APCcodes or the website. Thus, at a decision block 423, the dual codeverification system determines if the transmitted and received APC codessubstantially match one another. If they do match, the process 400proceeds to a block 424, and the user is verified and allowed to log into the website. If the user enters an incorrect APC verification code,the process 400 proceeds to a block 426, and the registration processmay stop and the user may be denied further access to the website,depending on the verification-requesting-website's preferences.

As described above, a problem with on-line registration is that the useror registrant often registers with untraceable and/or false e-mailaddresses and telephone numbers. The present invention provides aprocess for verifying an on-line registration using an additional layerof security by requiring a dual code confirmation process using theregistrant's own handset, cellular telephone, or similar device, inaddition to entry of a username and password alone. By requiring theregistrant to send the first electronic message to the system, theactive-status of the phone number that will be associated with theregistrant, as well as the accuracy of the phone number where the secondCODE will be communicated to can be further verified. In the event ofregistrant verification failure, it is assumed that the registrant whois not verified through the verification system or similar manual meansis fraudulent. Thereafter, the website owner may elect to contact theregistrant to determine why the verification failed. At that point, thecontact may be completed by automated or manual means of communicationbetween the website owner and the registrant, including, but not limitedto, automatically generated e-mail, manually generated e-mail, manuallyor automatically generated telephone calls, or text messaging.

FIG. 5 is a flow diagram of a process 500 for verifying a user who haspreviously successfully registered with a website. In this embodiment,the user is returning to the website for a subsequent visit ortransaction. At a block 506, the previously-registered user logs in tothe website requiring verification with his or her username andpassword. The user's handset or cellular telephone number, or contactinformation for a similar SMS-capable device, is already on file withthat website. After the user logs-in to the website, the websiterequests an IPC from the system, which, at a block 508, generates theIPC. At a block 510, the IPC is passed back to the website for display.In some implementations, the website generates the IPC, passing thatinformation back to the system. The IPC may be solely alphabetic, solelynumeric, or alphanumeric and is displayed on the website. At a block512, the dual code verification system displays a message on the websitethat prompts the user to send an SMS message containing the IPC to acontact number that is also displayed on the website. The user isfurther prompted to send the SMS message using his or her same mobiledevice (e.g., handset or cellular telephone number, or other similarSMS-enabled device telephone number), which was already previouslyregistered with the website upon initial registration, displaying atleast part of that registered device's phone number on the website. At adecision block 514, the system determines whether the user has sent anSMS message containing the IPC to the contact number displayed on thescreen using his or her registered SMS-capable device. At a decisionblock 516, the telephone number of the device sending the SMS message isverified against the telephone number already on file with the websiteby either the system or the website. At decision block 516, the systemeither looks up the IPC to ensure it matches with the generated IPCoriginally presented to the user or passes the IPC SMS message sent bythe user to the website to verify that the IPC code matches. If both thetelephone number and the IPC match, at a block 518, a secondverification code or APC is generated either by the system or by thewebsite. At a block 520, the APC is returned back to the user'sregistered handset or cellular telephone, or other SMS-capable devicetelephone number via return SMS message. At a block 522, the user isprompted to enter the APC into the on-line registration form. At adecision block 523, the transmitted and received APC codes are compared.The verification and authentication process is then completed when thetransmitted APC code substantially matches the received APC code. If theentered APC verification code is correct, at a block 524, the user isallowed to log-in to the website. If the APC verification code isincorrect, at a block 526, the log-in process may end and the user maybe denied access to the website, depending on theverification-requesting-website's preferences.

The described system performs a verification and authentication process.In some implementations, it comprises the steps of: providing aregistration form to a registrant through the registrant's first device;at least partially completing the registration form; communicating afirst verification code and system electronic contact to the registrantfor verification; verifying the registrant, including aregistrant-established connection inputting the first verification codethrough the registrant's secondary device; secondarily verifying theregistrant, including generating a second verification code, andestablishing a connection with the registrant via the registrant'ssecondary device used to communicate the first verification code;communicating the second verification code to the registrant; andinputting the second verification code into an on-line form or otherverification system.

From the foregoing, it will be appreciated that specific embodiments ofthe invention have been described herein for purposes of illustration,but that various modifications may be made without deviating from thescope of the invention. For example, those skilled in the art willappreciate that the depicted flow charts may be altered in a variety ofways.
